Voiced by: Hiro Shimono (anime, teenager),
Megumi Matsumoto (anime, child) : The protagonist of the series, with a gentle appearance and slim profile, Haruka, in many ways, is the spitting image of his fraternal twin sister, Sora. Personable and honest, he forges lasting friendships with remarkable ease. Haruka copes with the loss of his parents with a stout heart, burdened with the knowledge that the future of his delicate sister depends on him. He cannot swim.

Voiced by: Hiroko Taguchi (game [credited as "Shiranami"], anime) : She is a quiet, fragile and reclusive girl, fraternal twin sister to the protagonist. Frail since birth, Sora was denied the sort of independent life that many take for granted. Yet beneath Sora's angelic doll-like appearance lies a troublesome personality prone to emotional withdrawal, intellectual and physical laziness, and a severe lack of social graces. She spends most of her time surfing the Internet and eating crisps and instant food, so long as Haruka is by her side. Her strong bond with her brother strengthened as a result of the tragic loss of their parents and a kiss they shared as children, leads her to fantasize about incest, and she goes to great lengths to seduce him or at least to get him to spend more time with her. She hates Nao due to Nao raping Haruka, although it is implied that they were all once good friends. She is often seen clinging to a stuffed rabbit toy, which she received as a present from her mother before she died, which lends her a deceptively childlike character. ; :
Voiced by: Yuka Inokuchi (game [credited as "Ayaka Kimura"], anime) : Beautiful, intelligent and an excellent swimmer, Nao is Haruka's next-door neighbor and childhood friend, one year older than Haruka. When the Kasugano twins last visited the area, their departure was particularly painful for Nao, who, for some reason, had grown quite close to Haruka after having raped him on one occasion, about which she expresses guilt. Upon their return, she rekindles their former close relationship. Nao's compassion and maturity project a sense of sisterly love towards others, though for Haruka, there is a deeper and more intimate feeling. In her route and in the anime, she has a relationship with Haruka where at first Sora disagrees and even hates her, but after Nao saves her stuffed rabbit from a fire she seems to accept their relationship. In the end, Haruka and Nao make love while everyone else watches the fireworks. ; :
Voiced by: Mana Tsukishiro (game), Kayo Sakata (anime) : Akira is Haruka's energetic classmate with an innocent personality that makes befriending the girl second nature. Her enthusiasm is contagious to those around her. She was orphaned as a baby and taken in by the keeper of the local
shinto shrine and raised as his granddaughter when none of her more distant relatives were willing to take her. Although still a teenager, Akira has been the only
miko and shrine keeper since her foster grandfather died. She spends much of her time practicing the habits and traditions, including performance of requisite ceremonies and holiday festivals. She also devotes much of her time to helping the elderly in the village, making her beloved by all. It is strongly implied that she is the illegitimate daughter of Kazuha's father. In her route and the anime, she and Haruka start a relationship, but it is Akira herself, due to her insecurities, who tries to end it, but Haruka prevents her and tries to help her. In the end, after Haruka helps Akira find out who her real mother is, she thanks him, and they both resume their relationship and make love while promising to be together forever. ; :
Voiced by: Ryōko Ono (game [credited as "Nazuna Gogyo"], anime) : Haruka's classmate, the beautiful daughter of an influential magnate, Kazuha lives a cultured life that could be compared to that of a modern princess. Sharp-minded and attentive to detail as a result of her parents' constant travels and long-distance liaisons, she learned from a young age to behave responsibly, as befitting her social standing. Nevertheless, Kazuha does not consider herself superior to others and doesn't hesitate to lend a helping hand whenever asked. Kazuha is an experienced
viola player, yet she shies away from competing, preferring to play only for those she cares for. She dotes on Akira constantly and worries excessively for her well-being, and this leads to some speculation that they may be romantically involved. It is revealed (implied) that they are half-sisters with Kazuha referring to Akira as sister. Kazuha's excessive concern for Akira stems from her desire to make up for her mother's refusal to acknowledge Akira's existence and her father's apparent neglect of her. In her route and in the anime, she and Haruka fall in love. In the end, Haruka manages to overcome the problems with Kazuha's father because she thought he was ignoring his half-sister Akira, and Kazuha also manages to start a relationship with Haruka, eventually playing a song on the viola that they remembered because they made love while listening to the song.

Voiced by: Yukari Minegishi (game [credited as "Airi Himekawa"], anime) : Representative of Haruka, Ryouhei, Kazuha and Akira's class, often nicknamed "class rep". She fell in love at first sight with Haruka due to his gentle profile and appearance. Kozue is seen by others as a shy but serious person who is also very polite, but through her shy and responsible appearance, she has a "delusion mode" in which she imagines being in a romantic relationship with Haruka due to her crush on him. In Sora's storyline, she and Nao are the ones who later catch the twins having sex, and she can't accept their relationship the most due to her feelings towards Haruka. At the end of the final episode, she questions Nao if she is in love; all that matters is her feelings. In

Voiced by: Ryōko Tanaka (game [credited as "Hikaru Isshiki"], anime) : Best friend to Motoka Nogisaka and proprietor of a family-owned candy store, the rough-looking Yahiro would prefer spending her time sleeping and drinking. In truth, her ill-tempered and sardonic mannerisms hide Yahiro's true personality: a woman whose past is littered with lost dreams, forgotten promises, and broken romances. She has been Akira's unofficial guardian since her foster grandfather died and none of his relatives were willing to look after her. In an attempt to understand the undercurrents that he perceives surrounding Akira and Kazuha, Haruka persuades Yahiro to explain that, unbeknownst to the other characters, Akira's father has been aiding her financially since she had spent her savings from when she worked in the city as well as the scant earnings from the candy store to pay for Akira's education and other needs. In
Haruka na Sora, she shows a cuter side of her as a
tsundere in her route. ; :

While not ideally suited for household chores, her warm compassion and captivating personality offset these deficiencies. She is best friends with Ifukube Yahiro, a notoriously heavy drinker, which makes Motoka's low tolerance to alcohol a particularly hazardous social issue, especially since she has a particular fondness for the taste of sake. She is the star of the anime's omake bonus feature, in which she entertains people with her skilled impressions of other characters, and eventually falls in love with Haruka despite him being significantly younger than her. At the end of the omake, located in the final chapter, Motoka gets to marry Haruka, who is the only one of all the heroines who manages to do so. ; :
